2000 per week

From what I read, it looks like they produced closer to 10,000 units but only delivered about 8,000 in the first quarter.

“The company built 34,494 vehicles during 2018's first quarter — 9,766 of which were Model 3s. First-quarter deliveries of the three Tesla models also set a record with 29,980 vehicles — 11,730 were the Model S, 10,070 were the Model X, and 8,180 were the Model 3.”
